Refer to the exhibit. A customer requested that you conduct a performance evaluation test for migration of a DB2 database server to new Symmetrix VMAX storage. The test storage is configured as 20 logical volumes allocated on four FE ports to two HBAs in the server. Each volume is 50 GB and is configured as a 4 way striped meta. The results of the test indicate 20% less throughput than was expected. The exhibit shows results from the data collected during the time frame of the test. What is a likely cause for this performance issue?
